Hello..
A spider is a program that a search engine uses to seek out information on the World Wide Web, as well as to index the information that it finds so that actual search results appear when a search query for a keyword is entered. The search engine spider "reads" the text on the web page or collection of web pages, and records any hyperlinks it finds. The search engine spider then follows these URLs, spiders those pages, and collects all the data by saving copies of the web pages into the index of the search engine for use by visitors.
Thnx...

hi,

spider is a software.
Spiders follow links from one page to another and from one site to another. That is the primary reason why links to your site are so critical. Getting links to your website from other websites will give the search engine spiders more opportunities to find and re-index your site. The more times they find links to your site, the more times they will stop by and visit.
